Haas Settings: 108 – Quick Rotary G28

Turning this setting ON will return the rotary unit back to zero using the shortest distance.
For example if the rotary unit is at 10° and a zero return is commanded, the rotary table will rotate 350° if this setting is OFF. If the setting is ON the table will rotate -10°.
In order to use Setting 108, the parameter bit CIRC. WRAP. (10) must be set to 1 on parameter 43 for the A axis and Parameter 151 for the B-axis. If parameter bit(s) are not set to 1 the control will ignore setting 108.
